BWSENSING Dual Axis Wireless NB-Iot Inclinometer (NB-WL300)

A leaning wall does not send a letter. It moves a little each season, and the people responsible for it usually learn about the movement only when somebody drives out to look. The BWSENSING Dual Axis Wireless NB-Iot Inclinometer (NB-WL300) is built to end that wait: it measures tilt on two axes and sends the reading to the cloud over a cellular network, so the site reports to you instead of the other way around.

Background

The company behind the sensor

BWSENSING is the global brand of Bewis Sensing Technology LLC, a company established in 2010 and describing itself as innovative and fast growing. From 2019 the BWSENSING name has been approved as the company's global brand, which is why you will see it on inclinometers, tilt sensors and related monitoring products across many markets. For a buyer in the Caribbean, that means a manufacturer with a defined product line rather than a one-off device, and a family of related sensors to choose from when a project changes shape.

Inclinometers are a quiet but important part of structural and geotechnical monitoring. They measure angular deviation, and when several are read over weeks and months they show whether a structure is steady or slowly shifting. The BWSENSING catalog covers a wide range of these instruments, and you can browse the wider BWSensing range or the general Sensors category to see how the NB-WL300 sits among them.

Positioning and key technology

The NB-WK100 and NB-WL300 form a high cost-effective wireless tilt sensor pair that supports two network modes: NB-IoT and GSM. The NB-WL300 is the dual-axis model of that pair. Structure data can be uploaded to the cloud through NB-IoT or through the operator's 2G network, so the sensor is not tied to one kind of coverage.

Two further features shape how it is used. First, it charges from the sun, which suits locations where nobody wants to run a power cable. Second, it works with a customizable monitoring cloud system, so the readings land in a platform that can be set up around the project rather than a fixed screen that every customer must accept as it is.

What makes the NB-WL300 different from a wired inclinometer?

A wired inclinometer is a fine instrument when there is a data logger, a power source and a cable route nearby. Many monitoring points have none of these. A slope far from the road, a tower footing across a field, or a retaining wall behind a property may be easy to measure and hard to connect. The NB-WL300 removes the cable from the picture: it charges by solar power and reports over NB-IoT or the operator's 2G network.

The second difference is the choice of networks. NB-IoT is a low-power cellular technology made for small packets of sensor data, and 2G-GSM gives the sensor a second way to reach the cloud. If a site has one kind of coverage and not the other, the sensor is not stranded. The maximum transmission distance is no limit, which fits a device that relies on the cellular network rather than a local radio link to a gateway.

The third difference is what happens to the data afterward. Instead of collecting readings by hand, you receive them in a customizable monitoring cloud system. That matters for anyone who has to show a client, an engineer or an inspector how a structure has behaved over time.

What do accuracy and resolution tell you about this sensor?

The NB-WL300 has an accuracy of 0.1° and a resolution of 0.0007°. The two figures do different jobs. Accuracy describes how close a reading is to the true angle. Resolution describes the smallest change in angle the sensor can register. A fine resolution helps you see the direction of slow movement, while the accuracy figure tells you how much weight to give each absolute reading.

Because the unit measures on two axes, one device can follow a lean in more than one direction. That is useful where a structure might move forward and sideways at the same time, as an embankment or a foundation can after heavy rain. Both figures belong to the NB-WL300 only. The sibling model NB-WK100 is named in the same product description, but this page does not borrow any figure for it, and you should ask for its own datasheet if you are comparing.

Who is the NB-WL300 for?

Civil and geotechnical contractors are the clearest audience: they need to watch a slope, wall, bridge element or excavation over a long period without posting a technician at the site. Utility and infrastructure owners have the same problem across many scattered assets, and a cellular tilt sensor lets one office keep an eye on all of them.

Consultants and monitoring service providers will value the customizable cloud system, because it allows the data to be presented in a way that suits each client. Municipal teams and port or coastal authorities in the Caribbean, where ground, weather and exposed structures make steady observation worthwhile, can also use it for assets that are hard to visit.

If your site has a cable route, a logger and no need for cellular reporting, a wired model may suit you better. Dual-axis alternatives from the same brand include the BWSENSING Cost-Effective Dual-Axis Inclinometer (BWM427) and the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427). If you only need one axis, the BWSENSING Cost-Effective Single-Axis CAN Output Inclinometer (BWM415) is another option. Our team can help you compare them against your site.

What is the NB-WL300 used for?

1. Slope and embankment monitoring: watch for slow tilt on earthworks that are hard to reach after rain.
2. Retaining wall observation: track whether a wall leans further over time and in which direction.
3. Bridge and tower structures: follow angular change on elements where a cable run is impractical.
4. Foundation settlement checks: record tilt near excavations or new construction that may affect neighboring structures.
5. Remote asset surveillance: report the angle of equipment or structures spread across sites with no local network.
6. Long-term reporting to a cloud platform: build a history of readings that engineers and clients can review without visiting.

Frequently Asked Questions

What does the NB-WL300 measure?

It is a dual-axis tilt sensor, so it measures inclination on two axes, with an accuracy of 0.1° and a resolution of 0.0007°.

Which networks does it use?

It supports NB-IoT and 2G-GSM. Structure data can be uploaded to the cloud through NB-IoT or the operator's 2G network.

How is it powered?

It charges from solar power. Ask us about the power supply and battery capacity when you request a quotation.

What is the maximum transmission distance?

The maximum transmission distance is no limit. The sensor reports over cellular networks, so coverage at your site is what to check.

Can I see the data in my own system?

The sensor works with a customizable monitoring cloud system. Tell us how you want the data presented when you request a quotation.

Is the IP rating or operating temperature known?

Neither is given in the figures we hold. Tell us about your site and we will settle both with you before you decide.

Where can I buy the NB-WL300 and what does it cost?

You can request it through this page. The cost is given in a quotation that also covers delivery, customs and support, and no price is shown here.

Summary

Slow movement is easy to miss and expensive to ignore, and the hard part has always been getting the reading back from a remote site. The NB-WL300 answers with dual-axis tilt measurement at 0.1° accuracy and 0.0007° resolution, solar charging, NB-IoT and 2G-GSM connectivity, and a customizable monitoring cloud system. If you have a structure that needs watching from a distance, this page is the starting point.
